NUT-LOCK FOR RAIL-JOINTS.

SPECIFICATION forming part of Letters Patent No. 273,029, dated.February 27, 1883.

Application filed December 16,1882. (ModeL) the contrivance being verysimple and cheap to make, and being calculated to afl'ord sub stantialand permanent security to the nuts,

' at the same time being capable of removal and reapplication withoutdamage to anyof the parts, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of a rail-joint with my improved nut-lockattached. Fig. 2 is a horizontal section of Fig. l on line a: m. Fig. 3is a transverse section on lineyy. Fig. 4 is an elevation of the notchedplate. Fig. 5 is a perspective view of the key, and Fig. 6 is aperspective view of a portion of the looped plate by which thelocking-plate is secured.

In the first place, I apply a plate, a, having loops 1) at the middle,or thereabout, to the bolts 0, and secure it by the nuts 61 firmlyagainst the side of the joint-plate e. I then apply a locking-plate,f,having notched or forked ends g and notches h, to the said loopplate,and then secure said plates together by a split or bent spring-key, 2,passed through the loops b, around or outside of platef, thus firmlysecuring the locking-plate, which, by its notches g fitting the sides ofthe nuts, securely fastens them against turning loose. I prefer to makethe loop-plate by punching out a portion at forming aslot as long as 01'a little longer than the loops are to be,and then bending up the loops,as shown, said loops being thus made a suitable distance apart for thenarrow portion It of the locking-plate to drop in between them. Ipropose to make the lower prongs, m, of the locking-plate to extend downsufficiently to bear on the base it of the jointplate or rail forresting thereon, making them longer than the upper prongs, if required.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a nut-lock for rail-joints, a plate, a, havingloops 1), slot j, and holes for the jointbolts, and being secured to theside of the joint-plate by the joint bolts and nuts, substantially asdescribed.

:2. In a nut-lock for rail-joints, a forked or flanged plate,f, havingnotches h, and being secured to the looped plate by a key, 2',substantially as described.

3. In a nut-lock, the combination, with the joint bolts and nuts and theplate a, having loops 1), slotj, and holes for the joint-bolts, of theforked plate f, having notches h, and key '5, substantially asdescribed, and for the purpose set forth.
